ABSTRACT:
Apparatus for controlling the transition of a number of lasers that are transmitting light to an optical bus from an off state to a sub-threshold bias state so as to minimize the transmission of light from lasers in the sub-threshold bias state. The apparatus places each laser in the sub-threshold bias state a predetermined time before it is to transmit data to the bus; and then, the apparatus places each laser in the off state after the data transmission has occurred. The lasers transmit in a sequential order onto the optical bus.
